Removing particles using opacity bitmap

[Pablo]

Hi all!
Does anyone know a way to remove the appearance of particles from geometry using a bitmap (Opacity map)? So that particles do not appear on black parts.

Surface test have an texture option.
Just add a surface test, pick an object, change to texture, adjust the options of you want it to detect bright or dark pixels, and just connect it to the new event containing just a delete operator.
